The present invention relates to certain improvements in that class of stamp-canceling devices in which the cancellation of the stamp is effected by mechanical and chemical means. The invention consists, chiefly, a mechanic al canceling device or stamp adapted to be used in connection with the ordinary single or double ranged that it will normally protrude beyond said postmarlring-stamp, and cause the rotation of 'a central `post when 'it is pressed upon the stamp to be canceled, for causing furrows or radial ribs on said central rotating The canceling-stamp consists, mainly, of an outer shell having a tubular guide-extension, which receives the upper portionof the grooved down by projections of the guide-extension 4entering the grooves in the post.

The shell of the stamp contains a springseated cushion-block having a central opening for the passage of the canceling-post.

The details of construction and arrangement will be hereinafter more fully vdescribed in connection withthe drawing forming part of Figure 1 is a side elevation of a combined canceling and postmarking stamp. Fig. 2 is a similar view of a single canceling-stamp. Fig. 3 is a detached view of the canceling device, and Fig. et isa top view of the stampcasing.

"Ihe lettery A denotes a cylindrical shell,

celing devices proper lof the stamp.I These consist-of a central post, B, having radial Ases@Ns-SIAMPS@g;

canceling-post, and cause thus the rotation of the latter 'when it is pressed upon a iiXed surface, or, in other words, when it is borne down upon the stamp to be canceled.

The shell contains a cylindrical block, F, which is provided with a central opening for the passage of the canceling-post B, the latter serving to retain it in position within the shell by enlarging the lower end of the cancelingpost. The latter is passed through the cushion-block from below, and is prevented from dropping out of the casing by means of a pin, b, passed through the upper end of the stem of the post. The block F acts as a cushion and ink-distributer, and may be provided with bottom grooves for the proper retention of the ink.

A spiral spring, G, arranged within the tubular extension of the shell, encircles the stem of the canceling-post, and a similar but larger spring, H, is arranged in the space between the top of the cushion-block F and the extension of the shell. These springs serve to project the cushion-block and canceling-post beyond the shell A, as is shown in the various figures of the drawing.

As shown in Fig. l, my canceling device is applied to an ordinary postmarking stamp, I designating the stamp, J the apertured supporting-arm, and K the handle.

When the canceling-stamp is used in this connection, it protrudes normally beyond the rigid postmarkingstamp, so that the necessary rotary motion can be given to the canceling-stamp, and both stamps made to perform their respective operations or give their impressions at the same time. In Fig. 2, the canceling-post .is fitted into a handle or holder, L, and is used without the postmarkin g stamp.

It will be perceived from the above description that Vmy canceling device or appliance is adapted for use in the single as well as in grooves 'furrows,- or -cutters 'on' its' 'lower 'sur-*f face, and 'provided A'with a 1 spirally: groove@ lm, fC, 1"which is' guided'in a tubular'cxtel'i-vw e Icylindrical shell Ar At ther said eXtensi'oiiffD' 'is' locatetla having projecting lips c, livhic'hI 9 enter the spiral grooves a in the stem of the the double hand-stamps generally used in it properly in'place.

4The cheapness and simplicity of construction commend my canceling device for universal use, and it is certain to effect a perfect cancellation of the stamp, both mechanically and chemically, at one and thelsame time, because it rips olf or inutilates the color, texture,

or surface of the stamp, and causes the saine to receive a proper amount of ink, so astoA preclude the possibility of the stamp being restored to its original state or used a second time.
